Biography
Dr. Khondaker received his Ph.D. degree in 1999 from Cavendish Laboratory of the University of Cambridge under the supervision of Professor Michael Pepper FRS. After finishing the Ph.D., Dr. Khondaker worked first as an assistant professor and then as an associate professor at the University of Dhaka, Bangladesh from 1999 to 2001. In 2001, he started a postdoctoral research fellowship at the University of Texas at Austin, where he worked on the nanoscale device fabrication and characterization. From 2003 to 2005, he worked as an assistant director at the center for nano and molecular science and technology at the University of Texas at Austin. He joined UCF in 2005.
Research Areas
My research group is interested in the fabrication of nanoscale electrical and optical devices consisting of low dimensional chemical nanostructures such as nanoparticles, nanowires, nanotubes, and molecules and investigation of their electronic transport properties. Nanoscience and nanotechnology deals with the study, development, and application of materials, devices, and systems with dimensions in the 1–100 nm range. The physical, chemical, and biological properties of materials at the nanoscale differ in fundamental and valuable ways from the properties of bulk matter. The many novel phenomena observed at the nanoscale are primarily the consequence of the appearance of quantum effects that begin to play an important role at length scales approaching a few nanometers. Our research effort is directed toward creating and characterizing improved materials, devices, and systems at the nanoscale that exploit these new properties. Specific areas of research interest includes: (i) Controlled assembly of carbon nanotubes and their device properties, (ii) Beyond Moors Law: Single electron transistors (iii) Chemically functionalized graphene: fundamentals and applications and (iv) Novel techniques for fabricating organic electronic and photovoltaic devices.
